What is a PDI and do I have to do one before taking possession?

A Pre-Delivery Inspection, commonly called a PDI, is a walkthrough of your new home with the builder before you take possession. It is a required step under Tarion's program and gives you the opportunity to document existing deficiencies — cosmetic issues, incomplete items, damaged finishes — before the keys change hands.

During the PDI, you and a builder representative complete a Tarion form listing every deficiency you find. Anything noted on that form is acknowledged by the builder as an existing condition, making it easier to have those items addressed under the builder's warranty. Items you miss during the PDI are not necessarily excluded from warranty coverage, but documenting them in advance strengthens your position significantly.

You are entitled to bring someone with you, and many buyers choose to hire an independent home inspector for the PDI even though the home is brand new. A trained eye can identify issues a first-time buyer might overlook.

After possession you have 30 days (and later one year, two years, and seven years, for different warranty categories) to report additional deficiencies to Tarion through their online portal. Do not skip or rush the PDI — it is one of your most important steps in a new-construction purchase.
